T.D. Williamson Asia Pacific Pte Ltd (TDW), a supplier of pipeline services and equipment, has announced completion of a challenging hot tap and folding STOPPLE® plugging operation on a critical water main in Ho Chi Minh City, Vietnam.
The operation, carried out for engineering design, construction and supervision consultants CDM International on behalf of Saigon Water Corp. (SAWACO), is the largest STOPPLE plugging operation TDW has performed in the Far East – Asia Pacific region. The STOPPLE plugging operation was carried out in conjunction with the Ho Chi Minh Environmental Sanitation Project (Nhieu Loc – Thi Nghe Basin).
The primary objective of the project was to install a storm water and sewage collector system to alleviate flooding and to correspondingly improve the water quality of one of the city’s primary canals by diverting sewage flows to a pumped collector system and by dredging the canal to promote natural tidal flushing.
